From The Stargate Omnipedia

Conflict spurred by Colonel John Sheppard's early awakening of all Wraith in the Pegasus Galaxy.

With the galaxy's inadequate amount of humans to sustain their entire population, Wraith factions began to form for the express purpose of gaining access to any attainable territory -- where a sparse food supply existed to begin with. Because the next Great Holocaust was undoubtedly some time away, the Wraith began to panic -- with stronger groups destroying the weak.
